The inner side of the lotion pump nozzle is designed, there will be three slots at the indication, and the liquid will be sprayed from three directions separately. If the design of this place is too large or too small, it will affect the spray. When the liquid is pumped up from the bottom, it will pass through the relatively narrow groove here, which will create certain resistance, and then spray through the three grooves of the nozzle head. There is a certain relationship, but if it can really change the effect of the spray, the design of the nozzle is very important.

    The design of the turning point of the nozzle should be reasonable. If it is too thick, the sprayed liquid mist cone is also relatively small, but it will spray farther. If the nozzle is designed to be thinner here, then the sprayed liquid will be more tapered. If it is large, it will expand and spray evenly, but it will not be sprayed too far.

    C angle needs to be chamfered at the outlet at the bottom of the inner side of the nozzle. If the chamfered angle is small, the taper of the spray is relatively small. If the chamfer is relatively large, the cone of the spray is relatively large. Generally, the shape of the nozzle can change the shape of the spray.

    There is a pillar in the pressure handle, which is matched with the nozzle. If the fit is too loose, it will easily fall out, and if the fit is too loose, the liquid will flow out from all around, which will not play a role in resistance, and the spray effect will not be very ideal.
